SPECIFICATION forming part of Letters'Patent No. 517,019, dated March 27, 1894; Application filed May 12, 1893. SsrlalNo. 474,013. (No model.)

To all whom t may concern:

Be it known that LFRANKBENA, a subject of the Emperor of Austria-Hungary, residing atSt. Louis, State of Missouri, have invented certain new and useful Improvements in Tricycles; and Ido lhereby declare the following to be a full, elear, and exact description of the f described, reference being had to the accom-- panying drawings, in which- Figure l is a side elevation of a tricycle embodying my improvements, one of the front wheels being removed. Fig. -2 is a perspective View illustrating the steering vgear and its connection with the propelling lever. Fig. 3 is an elevation of the drive wheel axle, one of the chain driving wheels, part 0E the main driving wheel and the clutch mechanism for locking the main driving wheel to its axle, and Fig. 4. is-a sectional elevation of the parts shown in Fig. 3.

Similar symbols indicate like parts wherever such may occur in the several'gures of drawings described, and in these W, indicates the main driving wheel, which, as shown, has two hubs 1 and 2, loosely mounted on the wheel axle A, but held against endwise motion thereon by means of two bolts, 3 and 4, extending into peripheral grooves 5 and 6 respectively, formed in the axle A, as shown in Fig. 4.. The outer face of both hubs 1 and 2 is provided with clutch teeth, Fig. 3. Upon4 the main axle A is loosely mounted the smaller chain-wheel w, but so connected as to rotate. therewith, as by a spline or feather 7, the invl ner face of the hub 12 being also provided;` with clutch teeth adapted to engage corresponding teethon main wheel hub 2. On the 5o outer ends of the axle are loosely mounted ft'wo hubs or bearings 8 and 9, to which is seother suitable manner.

cured one end of a' reach R, and R', held in position by suitable washers' and a pin'extending through the axle, or a nut 10, or in any A coiled: spring 13 on axle A, between the'reach bearing 9 and smaller chain wheel w tends'to hold said wheel in a normal positionto engage the clutch teeth- Y on the face of the hub2 of the main-driving wheel, yet allowsithe chain wheelw to move outwardly underpressure. A coupling'sleeve O is loosely mounted on main Wheel-axle A, and provided with clutch teeth adapted to engagefthe' corresponding t'eeth'on hub 1 of main driving wheel W, and between .said sleeve C and the bearing 8`for reach R is arranged a coiled' spring 14, whoset'ension is exerted upon sleeve() to hold the same in engagement with the hub 1 of main Wheel'W. A lever L', terminating lat one end in a handle 15 and at the otherin a ring 16 serves'to move theclutch sleeve C, and is secured in its respective positions in notches 18 and 19, formed in a lever support or slotted arm 17 secured to the seat springor support 20, Figs. 1 and 2. The ring 16 of lever L may be loosely mounted on the sleeve O, and held against outward motion by means of radial lugs 21 on said'sleeve C, so that when the lever L is moved inwardly or t'oward the main Wheel into notch 19 the sleeve Vwill be moved outwardly or out of nengagement With the hub 1 of the main driving wheel-W, and when s0 disengaged said main driving wheel-will revolve freely on axle A, as the clutchfteeth'on its hub 2 will then ride over'thelike teeth on the hub of chain wheel w, when the latter is held against rotation.

In order to prevent any clattering or noise which might result from the sliding of the clutch teeth on the hubs 2 and 12 over each Y other, the peripheral grooves 5 and are preferably made ot such width'asto admit of sufficient endwise motion otv the main wheel W on the axle A so 'that its `hub 2 will be practically out of engagement'with'the hub l2 of thechain wheel w, without moving the hub 1 into engagement with the clutchsleeve C when said sleeve has been moved outwardly against the stress of itsv spring 14,'that is to say, when the lever L is moved into notch 19. As clearly shown in Fig. 3, the pitch of the IOO teeth on the hubs l, 2, and 12, and on the coupling sleeve C, lies in a direction opposite to the direction of rotation of the vehicle wheels, so that when chain wheel w is revolved in the direction of its arrow Fig. 1, it will revolve the main wheel W in the same direction when the clutch faces are in engagement. This clutch mechanism basa two fold purpose, first to throw the driving mechanism out of operation on down grade travel, and secondly to admit of the stoppage of the vehicle by throwing the driving mechanism out of operation and immobilizing the main operating lever hereinafter referred to. It is obvious that the clutch lever ring 16 may be fitted in a peripheral groove formed in the clutch sleeve C, whereby said sleeve is moved positively by said lever in either direction, though this is not necessary, since the spring 14 will invariably move the sleeve inwardly whenever the lever L is moved out of the notch 19 into the notch 1S of the lever support 17. A special fulcrum for the lever L is also dispensed with, the reach R on which said lever has bearing serving as a fulcrum. The forward and rear ends 2l and 22 of both reachesR are twisted and bent into the form of springs, as shown in Figs. 1 and 2 for ob vious purposes, and said resilient front ends of the reaches are secured to a yoke or substantially U-shaped bar B that has at each end two bearings 23, 24, for the standards S, on which are formed the axles for the fore or steering wheels W', said axles projecting horizontally from a cylindrical boss 26 formed at the lower end of the standards and abutting against the lower bearings 24 of the yoke or bar B, the standards being held in their bearings by means of a retaining sleeve 26 keyed to their upper end. The yoke or U-shaped bar B is braced to the reaches R and R by means of braces rand r respectively, to which braces are secured the foot rests 27, one of which is shown in Fig. 1. The larger power transmitting chain wheel w' is loosely mounted on a short spindle s secured to a bracket 28 that depends from reach R', and said wheel is connected with the smaller chain wheel w on aXleA by means of a driving chain c. The spindle s of the power transmitting wheel w passes through the slot of one of a pair of slotted links 30 and the said chain wheel fw has a crank or wrist pin 29 that extends through the slot of one of said links 30, and is secured to the link by means of a nut, as shown, the other link being guided by and working on a stud s2 secured to a bracket 28n depending from reach R. The links 30 are formed on opposite ends of a cross-shaft 3l, that is pivoted in a bearing 32 at one end of a connecting rod 33 whose opposite end is forked and pivoted on radial pins 34 projecting from a ring or sleeve 35, through which the operating and steering lever L passes loosely, said sleeve being adjustable on the lever by means of pins 36 one above and the other below said sleeve.

To the upper end of the operating or working lever L is secured a pair of handles H, theframe37 for which is preferably U -shaped, as shown, whereby a better leverage is ob-l tained than would be the case if the handle bar were arranged perpendicular to the lever as in ordinary steering bars, and whereby said lever is more readily or easily revolved in operating the steering gear, the lever performing the double function of power and steering lever. The lower end of the said power and steering lever L is pivoted in the forked end ofa swivel stud or rock shaft 38, that has its bearing in a lug or ear 39, secured to the outer end of a slotted guide bar B', formed of two hat metal bars b and b so united as to form alongitudinal guide slot 40 in which the connecting rod 33 is guided, the opposite ends ofthe barbbeingbentdownwardly, theforwarddownwardlybentendconstituting the bearing for a crank shaft4l, an'tl the rear* downwardly bent end an arm 42, by means of which the bar is rigidly connected with the reaches R and R through the medium of a cross bar 48 secured to said reaches, see Fig. 2, and to said arm 42 is bolted or otherwise secured the more or less resilient seatsupport 20 to whose arms the seat S2 is secured, the forward arm being stiffened or braced by a flat bar 45, Figs. l and 2, to better support the weight of the rider.

On the swivel stud or rock shaft 38 is secured a link 46 whose lower end is slotted for the reception of the wrist pin 47 on the crank of the shaft 4l above referred to, said shaft having its bearing in the downwardly bent lug or ear 48 of bar section b, and in a stand ard s respectively secured to the yoke B and bar B', said standard serving at the same time as a support or brace for the forward end of said bar B. To the rear end of the rock shaft 41 is secured a second crank 49 whose wrist pin or bent end works in the slot of the lug or ear 50 projecting from a steering bar 5l between the outer forked ends of which is pivoted a radial arm 52 formed on or secured to the retaining sleeves 26 for the standards S of the short forward axles 25. It is obvious that when lever L is turned in sleeve 35 in one or the other direction, the rock shafts 38, and 4l, will be correspondingly revolved and the steering bar 51 moved in one or the other direction, thereby revolving the standards S and displacing the fore or steering wheels W from a straight line parallel with the line of travel, topa line at a greater or less angle thereto, and thereby changing the direction of the vehicle to the right or left of said line of travel according IOO IIC

to the direction in which the lever L is turned. By means of the described arrangement of remains practically unchanged, which would, however, not be the case, were the fore-wheels W mounted on a common axle adapted to be revolved about'a central pivot. The displacement of the axle from a plane perpendicular to the longitudinal axial plane of the vehicle would cause both of said wheels to more or less approach said axial plane, and correspondingly shorten the distance between said wheels and said plane, rendering the vehicle liable to topple over should the center of gravity of the weight of the rider be displaced toward one or the other side of the said longitudinal axial plane of the vehicle.

S is a leaf spring one end of which is connected with a shaft orbar secured in a bracket 53 bolted to the forward end of the reaches,

- the other end of said spring being connected with an arm that has bearing on the lever L, whereby said lever is automatically lifted from a depressed position in operating the driving crank 30, 3l. As above described the said driving crank 30 31 is a slotted crank, and performs the function of a lever of variable length, which enables me to apply the driving power centrally to the vehicle, and to distribute the leverage or power applied evenly on opposite sides of the longitudinal axial plane of said vehicle, which could not be done were the connecting rod 33 connected directly with the wrist pin on the chain wheel wf, as such crank would then have to be arranged on the outer face of the wheel, and one of the reaches would haveto be dispensed with. It is obvious that by means of the construction described, a brake mechanism can be dispensed with and the vehicle can be stopped by simply holding the lever Limmovable when the clutches are in engagement.

In order to assist the returning of the steering mechanism to its normal position, I employ thespring 54; securedto standard s, the arms of said spring having bearing on the opposite sides of the slotted lug 50 of the steering bar 51.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is
